Overview

 
The KML Viewer is an application for fast visualization of Geo Data1 and allows the user to save the result to any device without needing any other software.
 
1Geo Data is a data of the routes, the track logs and the waypoints.
 
You can upload recorded routes by GPS-tracker to the GIS Viewer. View Geo Data of your activities (run, walk, hike, drive) by yourself or share the result with your co-workers, your family and your closest friends even if you are far away from each other.
All you need is a GIS file in any of the supported formats:
  • gpx
  • kml, kmz
  • geojson, json, topojson
  • shp, dbf, shx, cpg, prj, qix
  • mif, mid
  • tab, map, id, dat
  • gdb, gdbtable, gbdtablx
  • gml
  • osm
  • csv
  • tif, geotiff
  • asc
Once rendered, the GIS Viewer allows to download the rendered Geo data in the popular raster or vector formats: PNG, JPEG, BMP, PDF, SVG.
basic features

GIS Viewer

  • Support many geo vector formats: Kml, Gpx, Tab, Shp, and more
  • Specify spatial reference system (EPSG code)
  • Specify map sizes
  • Zoom and move possibilities

KML Keyword Markup Language

KML (Keyhole Markup Language) contains geospatial information in XML notation. KML can be opened in Geographic Information System (GIS) applications provided they support it. Many applications have started providing support for KML format after it has been adopted as international standard.

How to use the GIS Viewer

  • Drop/upload a GIS file or select it from your cloud storage.
    !The remaining rendering parameters can be left as default. In this case go to step 6.
     
  • Select the render format from the drop-down list (the default format is PNG)
  • Select the render scale (the default scale is medium)
  • Select the Map reference system2 (the default system is Wgs84).
    Use a popular spatial reference system from a list or choose a custom system to enter the functioning EPSG code (4–5-digit numbers that represent coordinate reference system definitions) by yourself.
    We recommend choose "Undefined" to avoid repeated redefinition of the coordinate system (SRS).
    2Map reference system is a planar coordinate system that defines how the 2D projected map in your GIS relates to real locations on the Earth.
     
  • The GIS Viewer allows the user to adjust Map Rendering Settings for the most accurate result:
    - Map Width and Map Height are for setting the exact dimensions of the render scale,
    !In contradistinction to the three preset scales from point 3.
     
    - Padding is a padding from the edges of the image(map),
    - Warp Height and Warp Width are for changing the resolution of a raster image(map),
    - Extent.XMin, ExtentXmax, extent.YMin, Extent.YMax are to specify the bounds of a map to render. If no values are set, GIS Viewer automatically adds all objects from the GIS file to the rendered map.
  • Click the "Generate" button after all – GIS Viewer quickly processes and displays Geo Data on the screen. You can change the position and the scale of the rendered map with a computer mouse.
  • Click the "Download" to download the rendered file to any device, you can also save it to the cloud storage Drop Box or Google Drive by click the relevant links.
